Given numbers are 290,376,778,881

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 290,376,778,881 is 18684494680.

Find LCM of 290,376,778,881 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 145 x 188 x 389 x 881 = 18684494680

Therefore, the lowest common multiple of 290,376,778,881 is 18684494680.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

290 x 376 x 778 x 881 = 74737978720

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

290 : 1, 2, 5, 10, 29, 58, 145, 290

376 : 1, 2, 4, 8, 47, 94, 188, 376

778 : 1, 2, 389, 778

881 : 1, 881

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 290,376,778,881, is 1.

Now, the common factors can be found like this.

290:2x 5x 29

376:2x 2x 2x 47

778:2x 389

881:881

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2 = 4

Therefore, the value for common factors is 4.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 74737978720/(1x4)

LCM = 74737978720/4

LCM = 18684494680

Thus, we can understand that the LCM of 290,376,778,881 is 18684494680.
